If you never move ANYthing else to Flash, move the TSM DB there.   As someone 
else mentioned, it is like a religious experience.  Our expirations went from 3 
hours to 10 minutes.

I would actually keep DB and logs separate, avoid putting the DB on RAID-5 due 
to its high write penalty. We have our DB on 15K RPM SAS disks in 3x 4-disk 
RAID-10 sets. The logs we keep on RAID-1 collocated with the OS, since it's 
pretty low load and all sequential I/O.
